Keep auto restarting after hand sanitizer got in

I put the Note5 in my bag and the hand sanitizer accidently leak out, now the phone keep on rebooting after turning on for a few second until it runs out of battery. (it can reach the UI)

I tried to heat up the edge to over 100 degree with heat gun but still unable to open the back cover and the back glass ended up broken.

What should I do?
